The rockets rate of change in miles per second is:
(5 - 1)/(2.5*60 - 30) = 1/30 miler per second or 0.033
the rockets rate of change in miles per minute is:
(5 - 1)/(2.5 - 30/60) = 2 miles per minute
The correct answer is option B which is the value of Y will be 12.
<h3>What is an equation?</h3>
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
Given that:-
If the ordered pair (-5/2, y) lies on the graph of y=7-2x,
The value of Y will be calculated as:-
Y = 7 - 2x
Y = 7 - 2 ( -5/2 )
Y = 7 - ( - 5 )
Y = 7 + 5
Y = 12
Therefore the correct answer is option B which is the value of Y will be 12.

Answer:
(0,3)
Step-by-step explanation:
Step 1: 7x-2y=-6 Step 2: 7x-2y=-6 solve by elimination of the y value
2(8x+y=3)2 +(16x+2y=6)
Step 3: 23x=0, which means <u>x=0</u>
Step 4: subtitute 0 into the equation 8x+y=3
you get 8(0)+y=3, which comes to 0+y=3
you get <u>y=3</u>
therefore the solution to this system is (0,3)
